CSS3实现自定义Checkbox和Radiobox

我们知道浏览器自带的Checkbox复选框不怎么美观(这或许是我们看习惯了的缘故),而且复选框在不同的浏览器上显示的样式又有很大的差异,由 于目前越来越多的人开始接受支持CSS3的现代浏览器,所以今天就简单的用一些CSS3代码来自定义Checkbox的显示方式,个人觉得比浏览器自带的 Checkbox美观不少。(最底部有完整代码可运行)

下面先来看一下最终实现效果

效果图如下

 

下面来分析一下源代码,原理很简单,先把页面上<input type="checkbox" />的display设置为none,从而把它隐藏掉,然后利用CSS3代码来绘制与checkbox邻近的label元素:

<input type="checkbox" id="checkbox-1-1" class="regular-checkbox" /><label for="checkbox-1-1"></label>
<input type="checkbox" id="checkbox-1-2" class="regular-checkbox" /><label for="checkbox-1-2"></label>
<input type="checkbox" id="checkbox-1-3" class="regular-checkbox" /><label for="checkbox-1-3"></label>
<input type="checkbox" id="checkbox-1-4" class="regular-checkbox" /><label for="checkbox-1-4"></label>
.regular-checkbox + label {
    background-color: #fafafa;
    border: 1px solid #cacece;
    box-shadow: 0 1px 2px rgba(0,0,0,0.05), inset 0px -15px 10px -12px rgba(0,0,0,0.05);
    padding: 9px;
    border-radius: 3px;
    display: inline-block;
    position: relative;
}

下面的CSS代码可以让checkbox选中后出现阴影的效果,主要利用了box-shadow属性:

.regular-checkbox + label:active, .regular-checkbox:checked + label:active {
    box-shadow: 0 1px 2px rgba(0,0,0,0.05), inset 0px 1px 3px rgba(0,0,0,0.1);
}

radiobox的实现也是同样的原理,具体实现方式大家可以直接运行下面代码,也可以 下载到本地【  http://pan.baidu.com/s/1sl2Fxsp  密码: fzrq】,非常简单实用。
